• Question 93:

  A. Separate internal disk from the O/S
  B. Protected NAS share
  C. SAN volume
  D. Large SCSI-attached disk
  C. SAN volume

• Question 94:

  What is a key consideration when assessing a nested mount file system and an NDMP Volume Based Backup (VBB) backup strategy?

  A. Multithreaded PAX format for enhanced backup performance is supported
  B. Directory Direct Access Recovery (DDAR) for fast recovery is supported
  C. Selectively backing up a subset of the file system is unsupported
  D. Individual file recovery without the destructive restore flag is unsupported
  C. Selectively backing up a subset of the file system is unsupported

• Question 95:

  Refer to Scenario .

  A customer is looking to modernize their backup infrastructure. The current environment consists of a single centralized data center and several remote sites. The centralized data center hosts all core services and applications. The remote

  office primarily consists of sales personnel with 4000 use-North America, 500 in Europe, and 300 in Asia using file servers.

  The current backup environment at the primary site uses CommVault backing up to a Fibre Channel tape library that contains four ITO-4 tape drives. Currently they are backing up a number of file servers as well as several databases that

  have average change rates of 7% daily Remote office backups are currently performed by having users copy files to regional file servers that are then backed up to tape.

  In the past few months, the customer has expenenced problems with getting backups to finish within their defined windows as well as issues with the tape library hardware. They now have concerns about gaps in their backup coverage as

  well as the reliability of the tape media. In addition, an internal audit shows a large amount of user-generated data is unprotected on remote user laptops.

  The customer is looking for a common platform to standardize their backups. They want a solution which allows for a centralized infrastructure so -they do not need to rely on remote resources to address hardware and software issues. The

  other goal is to move away from tape to a more reliable disk-based solution.

  The customer is interested in Avamar to backup all their worldwide remote users. Based on best practices, which EMC solution will satisfy the customer's requirements?

  A. Deploy a single Avamar system at the primary location to back up all clients
  B. Deploy Avamar systems into each major geographical location, including Asia, Europe, and North America
  C. Deploy Avamar single-node systems at the remote sites and an Avamar system at the primary location as a replication target
  D. Deploy three Avamar grids to the primary location, each grid will be dedicated to a specific region
  D. Deploy three Avamar grids to the primary location, each grid will be dedicated to a specific region

• Question 96:

  You are performing a Data Deduplication Assessment for a customer. Which tool is used to test and tune network connections?

  A. iperf
  B. DDA:A
  C. DDA:B
  D. DPA
  A. iperf

• Question 97:

  A customer has a current EMC NetWorker LAN backup environment. The environment is using a local EMC Disk Library (EDL) with replication to a remote disaster recovery site. They want to introduce a four Data Mover Celerra into their environment for consolidated Windows user collaborative data on CIFS shares.

  Which backup deployment would you suggest that has the least disruptive hardware impact to the customer's current backup procedure?

  A. Implement a dedicated network link between two primary Data Movers on the Celerra and use NDMP three-way backup to back up to directly attached tape devices
  B. Utilize the Celerra NDMP2D feature on a second primary Data Mover and use NDMP-to- Disk backup to save the first primary Data Mover data to internally configured virtual tapes
  C. Implement a segmented dedicated backup network infrastructure and LAN backup the Celerra data to their existing backup servers
  D. Directly attach an EDL, through Fibre Channel, to the production Data Mover and use NDMP to back up the production Data Mover data to the EDL
  B. Utilize the Celerra NDMP2D feature on a second primary Data Mover and use NDMP-to- Disk backup to save the first primary Data Mover data to internally configured virtual tapes

• Question 98:

  The EMC account team has been asked to design a NetWorker backup solution for a Microsoft Exchange server. The customer's environment consists of a Microsoft Exchange Server 2007 Cluster Continuous Replication (CCR) deployment on a CLARiiON disk array with EMC VSS Provider and an EMC Disk Library. The customer wants to leverage the Microsoft VSS framework to protect the Exchange Server 2007 CCR environment. What needs to be considered when designing a backup solution?

  A. Microsoft Exchange Server 2007 system path and transaction logs must reside on separate directories.
  B. Exchange server can only be backed up through a Proxy Node.
  C. Microsoft Exchange Server 2007 database and transaction logs must reside on the same volume.
  D. Exchange server can be backed up from the Exchange Server 2007 CCR passive node.
  D. Exchange server can be backed up from the Exchange Server 2007 CCR passive node.

• Question 99:

  C. Disable cleaning
  D. Disable replication
  A. Reduce the read streams

• Question 100:
